How to remove the "Subscribe" button?

By default , the Actions window contains "Contact, Fave, Befriend, Greetings, Get E-mail, Share, Report Spam, Block and Subscribe". How to I remove one of them from displaying? I will like to remove the "Subscribe" from the list.

Next time post it under Dolphin 7.0 forum.

Run the following database query:

UPDATE `sys_objects_actions` SET `Caption` = '' WHERE `ID` = 10;
